The structural validity of the "Wechsler Intelligence Scale for Children-Fourth Edition" (WISC-IV) was evaluated using confirmatory factor analysis for a clinical sample of 1,537 students diagnosed with specific learning disabilities (SLD) by school psychologists in two large southwestern school districts. Results indicated that a…

Despite increasing rates of entry, students with learning disabilities (LD) continue to face barriers to completing post-secondary education. Faculty attitudes and knowledge are important factors in supporting students with LD, yet little is known about faculty preparation. No valid, reliable, easy-to-administer inventory exists to assess the…

This dissertation consists of four chapters. Chapter 1 provides an introduction to the self-determination literature documenting the importance of promoting the self-determination of transition and secondary age students with disabilities, as well as a summary of research examining the self-determination of students with disabilities across…

This study examined the scores on a state standards-based Grade 5 Science assessment obtained by a group of students without learning disabilities who took the standard form of the test and by three groups of students with learning disabilities: one taking the standard form of the test without accommodations or modifications, a second taking the…

The Illinois Test of Pscyholinguistic Abilities was administered to 167 normal intelligence children (mean age 112 months) and then factor analyzed to determine construct validity and the extent to which each subtest measures a discrete combination of the psycholinguistic dimensions of level, process, and channel. (DB)

The study examined correlations between the Wechsler Intelligence Scale for Children-Revised (WISC-R), the Peabody Picture Vocabulary Test-Revised (PPVT-R), and the Kaufman Assessment Battery for Children (K-ABC) for 44 learning disabled primary and intermediate special class students. The Mental Processing and Achievement scales of K-ABC…

Investigated nature of a learning disability index (LDI) for the objective assessment of verbal-nonverbal patterns of intellectual deficit on the Wechsler Intelligence Scale for Children-Revised using Factor II score coefficients derived from an unrotated principal components analysis of normative data, and average scaled scores. The…

Compared were the relationships between the Wechsler Intelligence Scale for Children and the Illinois Test of Psycholinguistic Abilities by means of the statistical methods of factor analysis and canonical correlation analysis as applied to scores of 63 children (mean age 7 1/2 years) referred for reading problems. (DB)

Among the findings was that the factor structure of learning disabled children on the Wechsler Intelligence Scale for Children-Revised was somewhat more fractionated and complex than for normals, but not as complex as for reading disabled children. (Author/DLS)

Examined factor structure of Conners Teacher Rating Scale (CTRS) in medically referred brain-damaged and learning-disabled children and adolescents. Extracted six factors: Conduct Disorder, Hyperkinesis, Distractibility, Depression, Dyssocial Behavior, and Introversion. Results support use of CTRS as brief objective instrument for assessing child…

Evaluation of the Frostig Developmental Test of Visual Perception found that it measured a single general factor of perceptual organization which was weakly related to IQ and unrelated to reading ability. (KW)

Investigated the construct validity of the 10 primary Illinois Test of Psycholinguistic abilities subtests in a clinical population of learning disabled children (N=91). Results via factor analysis and correlational analyses generally supported the independence of the channel dimension, i.e., visual versus auditory. The dimension of levels…

This study evaluated the construct validity of the Wechsler Intelligence Scale for Children, Third Edition (WISC-III) with children (ages 8 to 13) having learning disabilities who were either Hispanic (N=120) or Non-Hispanic white (N=120). Factor analyses found that the WISC III has a three factor structure consisting of verbal comprehension,…

A multi-faceted study followed up 800 children originally administered SCREEN, a comprehensive early identification screening battery. Ss were given an individually administered diagnostic battery: The Illinois Test of Psycholinguistic Abilities (ITPA), The Wechsler Intelligence Scale for Children (WISC) Verbal Scale, The Beery Visual Motor…

Analysis of Kaufman Assessment Battery for Children (K-ABC) Sequential and Simultaneous Processing scores of 94 children (ages 6-12) with learning disabilities produced factor patterns generally supportive of the traditional K-ABC Mental Processing structure with the exception of Spatial Memory. The sample exhibited relative processing strengths…
